WILLIAM F. HALL, OF RAYTOWN, MISSOURI.

OIL-BURNER.

Specification of Letters Patent.

Application filed December 15, 1910.

Patented Sept. 12, 1911. Serial No. 597,515.

To all whom it may concern:

Be it known that I, WILLIAM F. HALL, a citizen of the United States of America, residing at Raytown, in the county of J ackson and State of Missouri, have invented certain new and useful Improvements in OilBurners; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, ref erence being had to the accompanying drawing, forming a part of this specification.

The invention has for its object: first, the distribution, vaporization and burning of high grade petroleum oil, such as is known commercially as kerosene, and in the particular manner of its use forms one of the essential features of the invention whereby the flame from the burner is enabled to concentrate at its maximum degree of heat on a vaporizing tube above the burner. Second, to originate ignition of the vapor at the low point of the burner, and third, to prevent overflow of the oil in its initial supply to the burner.

The invention consists in the novel construction and combination of parts, such as will be first fully described and then specifically pointed out in the claim.

In the drawings: Figure 1. is a view in perspective of a stove, the forward portion and one end of the fire box, as well as portions of the top of the stove and smoke pipe being broken away to show the invention. Fig. 2. is a front view of the burner and vaporizing conduit or pipe, showing the deflection of the burner relative to the vaporizing pipe. Fig. 3. is a plan view in detail of the burner enlarged, showing the gas vents or orifices. Fig. 4. is a detail view, in perspective, of portions of the burner and vaporizing pipe, showing the vaporizing chamber, and in illustration the flame and its action upon the vaporizing pipe. Fig. 5. is an enlarged detail view, in perspective, of the receptacle for the overflow of the initial quantity of the oil for ignition, with the inner end partially broken away.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

Referring to the drawing, 10 indicates an ordinary cooking stove or range, to which the invention is particularly applicable, of which 12 is the fire box, with the front por tion shown broken away, 13 the smoke flue in the back portion and top of the stove or range, and 14 the smoke pipe or stack.

Within the fire box 12 of the cooking stove is arranged in the longitudinal direction of the box, the burner 15, and the longitudinally extended vaporizing conduit or pipe 16, having a vaporizing chamber 16*. The burner 15 consists of a longitudinallyextended flame-producing pipe or tube, smaller in circumference than the pipe 16, and which extends from a position adjacent to the left hand end of the fire box to within a short distance of the right hand end of the said box, and is positioned for the equal distribution of the heat a short distance above the grate 12, and equi-distant from the front and rear portions of said box and is provided with external screw-threaded ends 17 and 18.

Upon one end of the pipe or burner 15, in the direction of the right hand end of the fire box, is a small oval receptacle 19, extending downwardly below the line of the lower surface of the pipe 15, and having closed inner and outer ends 20 and 21, respectively. In the upper portion of the end 20, of said receptacle, is a screw-threaded opening 22, in which opening is fitted the screw-threaded end 17, of the burner. The receptacle closes the outer end of pipe 15, and forms a sup port therefor, on the grate of the stove in the fire box. In the upper surface of the pipe or burner 15, adjacent to the ends of said burner, are the longitudinal openings or slits 23 and 24. These slits or openings extend through the upper portion of the pipe, and are short in length, the outer ends of the slits terminating a short distance in wardly from the respective screw-threaded portions 17 and 18, of the burner. In the upper surface and central portionpf the burner 15 are the transverse openmgs or slits 25, which extend through the upper portion of the pipe, and similarly to the slits 23 and 24, communicate with the interior of the pipe or burner. The slits 25, of which a number are employed, are preferably spaced at equal distances apart from each other, and from the inner ends of the slits 23 and 24. Upon the screw threaded portion 18, of the other end of the pipe or burner from that having the receptacle 19, is fitted the reduced, internal screw-threaded lower end 26, of an elbow 27. With the upper, larger opening of the said elbow 27 is connected the lower, internally screw threaded end of a connecting pipe 28, and the upper end of which pipe, which extends upwardly a short distance, is also externally screw threaded and is fitted to the lower end of an elbow 29. Vith the opening in the other end of the elbow 29 is connected the externally screw threaded inner end of the vaporizing pipe 16, which is larger in circumference than the burner, and

located directly above said burner and at a' I pipe 31, which is short in length, its upper.-

end extending upwardly a. short distance above a. line horizontal with the upper portion of the back of the fire box, and with said end is connected, in like manner as V withthe elbow 30, an elbow 32. WVith the elbow 32 is connected the inner end of a pipe 33, the other end of which pipe extends toward. the rear end of the stove beneath the top and parallel with the inner surface of the front side of the stove, to a position transverse with the line of the flue 13, in 35 the rear portion of the top of thestove. Upon said end of pipe 33 is an elbow 34, and with said elbow is connected one end of I a pipe 35, the other end of which pipe extends at right angles to pipe 33 and to a position in line with the flue 13, and upon said end is an elbow 36. With the elbow 36 is connected the lower end of a pipe 37 the upper end of which pipe extends upwardly within the flue 13 and a short distance upwardly within the smoke pipe 14, and upon the upper end of which pipe is an elbow 38. i

40 indicates a reservoir for holding a supply of the oil to be burned. This reservoir is placed at a distance from the stove, and may be for safety outside of the walls of a house. With the lower portion of the reservoir is connected a distributing pipe 41, the other end of which pipe extends to and through the smoke pipe 14, and is connected with the elbow 38, within said pipe. In the pipe 41 is a cut-01f valve 42. i; In operation the reservoir 41 being supplied with oil to be burned, the valve 42 is opened to a slight extent sufiicient to admit of the passage to the burner 15 of a small quantity of the oil, to obtain initial heating of the vaporizing pipe 16. The small quantity of oil being permitted to passthrough the pipe 41', and past the valve 42, the valve 42 is closed, and the oil passes into pipe 35, thence into pipe 33, thence through the vaporizing pipe 16, to the burner 15, and upon reaching the bend 15*, the admitted quantity of-the oil moves past the bend at an accelerated speed to the receptacle 19, and fills the receptacle and the end of the burner up to a point below the slit 23, in the burner. The oil beneath the slit 23 only being ignited, the flame from the slit 23 is directed upon the vaporizing pipe 16 and the burner becomes heated. Before the flame from the slit 23 diminishes in height the valve 42 is again opened and the oil freely passes into the vaporizing pipe 16, 0 and becomes partially vaporized, the vapor entering the burner 15, and the non-vaporized oil passing to receptacle 19, as before. The vapor now ignites in the slits 25, from the flame from combustion of the oil in 5 slit 23, and the flame spreads, owing to the inclination of the burner, from the slit 23 to the first cross slit 25, then to the slit next adjoining, and so on, in the direction of the slit 24, which point being reached, the flames from the slits 25 have in the meantime increased the temperature of the vaporizing pipe to such a degree that the oil becomes vaporized upon the passage through the said pipe. The flames from slits 25 approach the vaporizing pipe 16 transversely to its longitudinal axis, and enveloping the vaporizing pipe, are subject to thedraft of the stove, which then car; ries the flame beneath the top of the stove over the top of the oven to the flue 13, the non-combustible elements passing up the smoke pipe 14. The intense heat from the burner serves to vaporize all of the oil passing to the vaporizing pipe, which has become heated in passing through the smoke flue 13, and the pipe leading to the vaporizing pipe, so that nearly complete com bustion results from the apparatus.

I am aware that the burners heretofore in like apparatus have been arranged beneath the vaporizing pipe and provided with slits. I have discovered however that until the vaporization becomes perfect in the vaporizing pipe that the disposition of the excess of the oil should be accompanied by an accelerated movement of the oil in the burner, and that complete vaporization is more readily maintained when the flames from the small area of the burner envelop the larger area of the vaporizing pipe.

Such modifications may be employed as are within the scope of the appended claim.

Having fully described my invention, what I now claim as new and desire to secure by Letters Patent is:

In an apparatus for burning oil, the combination with a horizontal vaporizing pipe, of a longitudinally extending burner tube located beneath and in the same vertical plane With the vaporizing pipe and smaller tube, and longitudinal vapor outlets at the in circumference than said vaporizing pipe, ends of said tube, one of the latter closely 10 a connectiondbetvgeen tliebadjacent engs of adjoining said receptacle.
